Hi,I'm hoping someone can offer a little help with checking spoke lengths before I order some spokes for a wheel build.I wish to build up some touring wheels using Velocity Dyad rims, a son28 centerlock disk hub and my Rohloff hub.

Looking at the diagram in the link that Alex posted (if it's the right hub), there is only 2mm flange offset, so perhaps the small difference in spoke length is correct. It might be fiddly to build a wheel with a 2mm dish, with the distribution of spoke tension that is recommended. I wonder if it's worth the trouble, but I can't really say.

Lets be honest, plain gauge no name stainless would probably be fine for my use but..........Wheels are something I dont mind spending extra on. I've had a great run from my wheelbuilder.com set and I'm hoping to replicate the trouble free existence I've experience I've had so far with them. If it wasn't that I don't want my Rohloff out of my sight, I'd just box and mail my hubs to wheelbuilder to once again take care of. The person I dealt with has left so I don't have the same confidence with regards to posting Rohloff and Son28 to America.

Interestingly enough, well for me anyway, they spec either Dyad or Velocity's 26" extrusion version the Aeroheat more than any other rim in their lineupof tandams and singles. Not suggesting that they dont with good reason prefer the cliffhanger to the Dyad for the Divide, but like so much of the limited detail they offer in their online communication medium, they lack information and reasoning whilst producing a premium priced product whose potential customersmight balk at someone making their decisions for them willy nilly. Wheres the spoke count and wheres the brand/model of the spokes? for starters.Wheres their half price frame and fork combos Lovely bits of kit for sure but a frustrating lack of detail for those like me that need a little convincing to part with huge wads of dosh.

Well, I'm not aware of any complete bike where the buyer gets to choose his own specification. I do know that Comotion will build wheels to your specification and customise just about anything else, because all the bikes are built in house, not mass-produced by some factory in Taiwan or China.

As a matter of fact, Neil Gunton had his wheels built with 40 spokes, but since you want Rohloff that will not be an option.

But all your ruminations have been about buying a frame, not a complete bike, and you've already acquired the major components, so, so what if the complete bike spec is not finely detailed.

My personal choice would be the Velocity Chukker - I have them on my Sabbath, they have a deep profile and are very strong.

Well actually I get the impression that Co-motion allow for a lot of customisation which is great and much better than most of the competition. My complaint is minor in that their floorshop stock standard, is on their website, might do with a little more detail which is where the devil is in Most of the bikes I've looked at online tell me which spokes and tyres (including size) they use/allow so I was a little surprised that they dont although it might come down to which company is offering the best price at the time. In fact to many buyers this is very important eg. Surly Ogres come factory with 2.35 tyres but the spec sheet informs the buyer they can fit up to 2.5's.As a Co-motion Rohloff Divide frame is available bare, options are always interesting to me right up until the last possible moment when I hit the buy now button.Frame weight would be nice to have as a comparison too. I suppose they dont want to frighten off potential buyers with the scare that is chrome-molly even if it is Reynolds tubing of a very high standard.

Purely on a humorous note, I downloaded the Divide Rohloff pdf from Co-motion and its spec sheet suggests DT540/Rohloff Hubs; Aeroheat Rims. Tyres: Continental Town and Country 26"x2.1. This is an interesting spec for a 29er.

Just laced up some 700c Cliffhangers to a pair of Deore disc hubs. Originally wanted some Psychos, but they only had 32h available when my hubs are 36h. I'm yet to tension & true, as my cheapie wheel stand is in a partial state of assembly undergoing some life saving mods.

They sure feel tough!

Hi Kym,where did you source the cliffhangers? And of course how much? What determined your purchase decision? The Dyads, are for me, a bit more of a known quantity and marginally lighter than the Cliffhanger. Pricewise , Jensonusa are about $52 from memory on the Dyads plus shipping of course but if I buy a frame through them, then there is no difference throwing in the rims. No suggestion the Cliffhanger arnt a great rim, I just want to see a similar bang for buck. I too will be using 36H.

I've been meaning to ask you about this but keep forgetting. Why do you think you need tyres this wide anyway? Are you planning a desert tour?

After my backroad experiences with 32mm tyres last tour I'll be taking the 2" tyres off the Pioneer and putting the 1.6" tyres back on. Unless most of your ride is going to be on soft unsealed roads, there is no sense in pushing fat, slow and heavy tyres.

The couple of times I've used Velocity rims I've ordered them through my LBS. They're basically their own distributor in Australia in so far as I can tell. I hadn't come across any online source for them.

My criteria basically was a wide 622mm/700c/29er rim. I'll admit straight out the bike build is more an exercise of form over function. I just wanted a bigger diameter wheel, being able to running lower pressures. The frame basically has clearances for 2.5" tyres, despite being a fairly plain looking with a traditional horizontal top tube. The build is intended to be a sort of homage to the old baloon tyred scorchers from the earlier 20th century.

I doubt these wheels will see the serious kilometres as you're intending yours, so I'm not sure how comparable our usage will be.

Hi Ron,yeah I want to try some off road touring.I actually want to follow in the tyreprints of some of Coops smaller tours.I hear ya and agree, theres little advantage on the tarmac to anything wider sized.Even on that though I wont be going back to the 1.1 high pressure tyres I used to run.The Moulton is fine for the tarmac and gravel trails but I need something that can tow a trailer off road for trips like the Munda Biddi and Mawson, which the Moulton isnt quite up to. Its great for what it can do and has vastly exceeded my expectations but it does have limits and I wish to go past them. Much taller and wider tyres I'm hoping will also make up somewhat for the lack of suspension I'm used to riding on an onroad dually.

Sounds great What frame are you going for Will you be having racks or fenders 2.5 tyres I thought I was being adventurous with the 2.35's (probably Schwalbe Big Apple Kevlarguard 29Er Tire 29X2.35 to start with) . I've hardly done any kilometers, serious or otherwise since I got to WA as my extra 10kg would suggest. I'm just now starting to shake a leg and make decisions with regards bike build. Doing nothing will kill me so gotta start planning the next tour.
